Abstract
Es wird ein Regensensor (10), insbesondere für ein Kraftfahrzeug vorgeschlagen, der eine Messstrecke (34) aufweist, die zumindest aus einem Sendemittel (12) zur Emission von Strahlung und einem Empfängermittel (32) zur Detektion von Strahlung gebildet ist, wobei innerhalb der Messstrecke (34) eine Scheibe () mit mindestens einer Oberfläche (22) derart angeordnet ist, dass die Ausbreitung der Strahlung durch auf der Oberfläche (22) befindliche Feuchtigkeit beeinflusst ist. Erfindungsgemäß ist zumindest ein einziges holographisches Element (20) zur Führung der Strahlung vorgesehen ist, das auf und/oder in der Scheibe (11) angeordnet ist, und die Strahlung (14) in Richtung der Oberfläche (22) derart ablenkt, dass ein Strahlungspfad (21) entsteht, der bei einer Projektion auf die Oberfläche (22) einen Winkel (Alpha) einschließt. A rain sensor (10) is proposed, in particular for a motor vehicle, which has a measuring path (34) which is formed at least from a transmitting means (12) for emitting radiation and a receiver means (32) for detecting radiation, wherein Measuring section (34) a disc () with at least one surface (22) is arranged such that the propagation of the radiation is influenced by moisture on the surface (22). According to the invention, at least one single holographic element (20) is provided for guiding the radiation which is arranged on and / or in the pane (11) and deflects the radiation (14) in the direction of the surface (22) in such a way that a radiation path (21), which forms an angle (alpha) when projected onto the surface (22).
